The wood of this species is heavy, very hard, strong, 

 close-grained, but checking in drying. The wood is used 

 for fuel, hoops, lumber, etc., The species is common and 

 widely distributed in Iowa, though the greater number of 

 trees are still young. The seed is inedible, being very bit- 

 ter, sometimes used to adulterate other nuts of the same 

 genus. Our specimens are from Johnson, Jefferson, Ring- 

 gold, Montgomery, Pottawattamie, and Shelby counties. 

 We have observed the species in Winneshiek, Appanoose, 

 Taylor, Page, and Fremont counties. The State Uni- 

 versity herbarium contains specimens from Delaware, Lee, 

 Story, and Cerro Gordo counties. Professor Pammel 

 reports the species from Woodbury, Boone, and Hardin 

 counties; Mr. Reppert from Muscatine county; Professor 

 Fink from Fayette county; Professor Macbride from Hum- 

 boldt, Dickinson, and Dubuque counties; and Mr. J. P. 

 Anderson, by note, from Lucas county. This species 

 grows best on the lowlands, but frequently occurs on the 

 uplands.
